23 Claims.

This invention relates to improvements in means for supporting, aligningand guiding a plurality o1 superimposed strips of paper, and means forsupporting'in interleaved relationship with the strips 01 paper, sheetsof carbon paper, and for utilizing all parts of the carbon sheets.

The invention has for its object the provision, in connection with anapparatus for supporting a plurality of strips of paper, means foradjustablysupporting a plurality of sheets of carbon paper interleavedbetween the strips of paper.

It is an object of the invention to provide, in

connection with a typewriter, means .for supporting a plurality ofsuperimposed strips of paper fed to the typewriter, and means foradjustably supporting a plurality of sheets of carbon paper interleavedbetween the strips of paper so that the sheets of carbon paper may beadjusted that the type of the typewriter will not strike upon the sameline at all times. In other words, the type may strike upon that part ofthe carbon sheet between lines formerly used.

It is also an object of the invention to provide, in connection with atypewriter, a frame for supporting a plurality of superimposed strips ofpaper adapted to be fed through the typewriter and by the typewriter,and to provide on this frame adjustable means for supporting sheets ofcarbon paper, and means to adjust the sheets or carbon paper withrelation to the supporting means.

It is a further object of the invention to provide an improved method bywhich the relationship of the carbon sheets and the strips of paper maybe regulated and the length of the sheets controlled so that the carbonportions that are used can be removed, the sheets readjusted in positionand the operation repeated.

These and other objectswill appear from the following description takenin connection with the drawings.

The present apparatus is adapted to be used in connection withtypewriters, but may be used with other instrumentalities to which aplurality of superimposed strips ofpaper is to be fed.

The typewriter is indicated by the numeral l and has'the usual platen 2.On this typewriter is supported in any suitable manner a frame, whichconsists of side bars 3, connected at their upper ends by means of across bar 4, and at their lower ends by means of a cross bar 5. Thesetwo cross bars are braced by means 01 braces 6, which are riveted bymeans of rivets I to .the cross bars and to each other by means of arivet 8. The lower end of theframe is provided with brackets 9, by whichthe side bars are suitably attached to the frame of the typewriter.

On the lower ends of the side bars and rotatably supported thereby is alower shaft it, which has thereon a pair of sprockets ll. thesesprockets is a chain l2, each of which operatively connects the lowersprockets II to another pair of sprockets l3 located on the upper shaftl4, rotatably mounted on the upper end of the frame upon two bars l5,each attached to one of the side bars by screws, not shown. Each shafthas thereon a pair of sprockets connected by means of the sprocketchains l2. The upper ends of these bars ii are connected by means of arod l8.

On the upper end of the frame and attached to the side bars is a guideplate II. This plate is attached to the side bars by means of rivets II,and has adJacent each end thereof a slot l9 adapted to receive one endof a guide pin 20, adjustably supported in the slot by means of a screw2| (Figure 4). These pins may be adjusted to and from each other, andserve to guide strips of paper 22 as they pass over a drum 23 mounted onthe shaft l4.

Supported on the front of the frame and by the side bars thereof, is acarbon supporting plate 24. This plate engages the side bars at eachend, and has struck up therefrom tongues 25, which fit behind part ofthe side bars for guiding the plate as it moves up and down on theframe. The frame is U-shaped, with the arms thereof projecting towardeach other, and it is the front arms of these side bars that are engagedby the carbon supporting plate and the tongues struck up therefrom.

l2 by means of pins 26. There are two of these pins, one attached toeach end of a flat spring 21, attached intermediate its ends to theplate by means of rivets 28 (Figure 10). The plate is provided withholes 26a to receive the free ends of these pins. These pin's passthrough links of the chains for supporting the plate on the chains. Eachpin is supported at one end by the flat spring, while its other end issupported by the plate when the plate is supported on the chains. Thechains are held in close engagement with the plate by means of loops 29.In the present instance there are two loops'ior each end of the flatspring. These loops prevent the-chain from pulling the pins out of theholes so there is no danger of the carbon supporting plate beingaccidentally released from the chains during the operation of theapparatus.

Adjacent each end of the plate 24 is a U-shaped slot 30 (Figures 12 and13). The arms of these slots project away from the ends of the plate sothat the arms of one slot project toward the arms of the other slot andare parallel therewith. On the front side of the plate 24 is a springstrip 3|, which has attached to each end a pin "a. The parts of thesepins on one side of the spring strip are adapted to support a pluralityof sheets of carbon paper interleaved between strips of paper, while theparts of the pins projecting 'on the other side of the spring stripserve to engage the plate 24 within the slots 30 to hold the springstrip in the slots in adjusted position with relation to the plate. Bythis means the carbon papercanbesoadimtedastocausethetypeto strike theportion of the unused carbon sheets between the lines previously struck.The parts of the pins projecting through the slots are indicated by thenumeral 82, and have thereon wash-- era 33 which serve to hold the pinsand the spring Around each of strip against the plate, but permit a freemovement in relation thereto.

The pins 3| a have thereon a plurality of circular notches 34 adapted toreceive a member, not shown, for holding the carbon sheetson the pins.The extreme outer ends of these pins are also provided with small pins35 to prevent the carbon sheets from slipping off of the pins 3la in theevent no other instrumentality is used for that purpose. Y

At the back side of the frame is,a paper feed plate 36, which isattached to the sprocket chains l2, as by the bolts 36a. The feed plate35 has at each end, on the upper edge thereof, a bracket 31 (Figures 4to 8 inclusive). These brackets support a guide rod 38 by means ofscrews 39 extending through the brackets intothe ends of the rod. Oneach end of the rod, adjacent a paper being used on the apparatus. Thedistance these discs are apart also corresponds to the distance the pins20 are apart.

The feed plate 36 also has on its lower edge,

at each end, a bracket 42 to which is attached one end of an arm 43 bymeans of bolts 44. The upper end of each arm 43 has a stop 45 adapted toengage the upper edge of the feed plate. To the stop ends of the arms 43is attached an angle iron 46, which has thereon aligning and feedingpins 41 adapted to pass through holes in the strips of paper and throughholes provided therefor in the upper edge of the feed plate. The angleiron is urged toward the feed plate by means of a spring 48 connected atone end to the angle iron and at its other end to the rod 38.

There is also provided on the feed plate intermediate its upper edgesand between its ends, brackets 49 which support a guide rod 50. Thisguide rod serves to hold the strips of paper against the feed plate.This rod also cooperates with the rod 38 in holding the strips of paperin proper position when the aligning and feeding pins are withdrawn fromthe holes in the strips of paper. I

The strips of paper are fed over the drum at the top of the frame from apile of paper 5|, located on some suitable support behind the typewriter. Each strip of paper is divided by means of cross perforations52, into sheets of sufllcient size for the desired use (Figure l)Adjacent the upper edge of each sheet of the strip are holes 53 forreceiving the pins 41. The carbon sheets are indicated'by the numeral 54and may be divided.

as shown in Figures 9, 14 and 15 into narrow strips by means of crossperforations 55. These narrow strips are indicated by the numeral 56,the width of which may be varied to suit the extent of the carbon sheetto be used. After any one of these narrow strips has been so used thatit has become worthless it may be torn oil.

The carbon sheets thus become shorter, and-in order to use the otherpart of the sheet it is necessary to lower the carmn supporting plate onthe chains. This is done by withdrawing the pins 26 from the chains sothat the plate may be slipped down. after which the pins may be forcedto engage another link in the chain, whereby the plate is againsupported in its desired position. when another of these narrow stripsof carbon is used it is torn oil and the plate is again lowered forfurther use of the carbon sheet. Each carbon sheet is supported bymeansof a narrow strip 51 composed of some suitable material. Usuallythis I 19,871 strip is made of some fibrous material, and has in eachend a hole I adapted to receive one of the I pins 3 la.

The lower end of each side bar is provided with a rubber stop disc 59engaged by the paper feed plate when it is in its lowest position, andwhen the carbon supporting plate is in its uppermost position. on one ofthe side bars without the frame is a spring housing 60 (Figure 11),which has therein a coil spring 6! attached at one end at the point 62to the upper shaft i I, and at its other end at the point 63 to thespring housing 60.

By adjusting the spring strip 31 on the plate 24 the point at which thetype engages the carbon sheets may be changed so that the whole of thecarbon sheet may be used. By varying the position of the plate 24 on thechains the whole length of the carbon sheet may be varied. When a longsheet is used this plate is attached to the chain near the upper end ofthe frame while the feed plate is engaging the stop. -With shortersheets of carbon paper the plate 24 is positioned on the chain a greaterdistance from the top of the frame, this distance depending upon thelength of the carbon sheet. When the carbon sheets have been used andthe lower narrow strips thereof torn off, this plate 24 is lowered sothat unused parts of the carbon sheets may be used.

' By means of applicant's apparatus everyavailable part of the carbonsheet is used, thereby avoiding waste and lengthening the life of thecarbon sheets and increasing the efficiency of the writing.
